Estimation Over Heterogeneous Sensor Networks

Free registration required

Executive Summary

Design trade-offs between estimation performance, processing delay and communication cost for a sensor scheduling problem is discussed. The authors consider a heterogeneous sensor network with two types of sensors: the first type has low-quality measurements, small processing delay and a light communication cost, while the second type is of high quality, but imposes a large processing delay and a high communication cost. Such a heterogeneous sensor network is common in applications, where for instance in a localization system the poor sensor can be an ultrasound sensor while the more powerful sensor can be a camera.
